Easily, the more I practice, the better I get. :) I juggle, and play guitar and piano. The more time I spend doing them, the better I get. Especially juggling, because it's pure repetition and motor skills. Whereas piano and guitar require learning new songs, progressions, and incorporate a few different tasks into the mix like technique and memorization. Juggling you pretty much just practice practice and then practice some more. It's 100% muscle memory and motor skills. EDIT: I should add, I've not practiced any of those things for anywhere near 10,000 hours obviously, it's just an expression. :) http://newswatch.nationalgeographic.com/2012/08/14/malcolm-g.../can you think of how the 10,000 hours model has applied to how you've improved on your personal talents?
